Ubiquitous communications and services, integral to pervasive computing and smart space applications, pose significant management challenges for delivering adaptive services across diverse networks and devices. Key issues include managing user-centric and context services, scalability, system and network heterogeneity, and intelligent support for applications. Current management systems must adapt to the complexities and automation demanded by pervasive computing. The MUCS workshop fosters collaboration between Ubiquitous Computing and Communications Management, offering a platform for researchers and practitioners to address theoretical, technological, and organizational challenges and to showcase advancements in management techniques for these applications. The 2011 workshop featured a single-track program with a keynote, peer-reviewed papers, and interactive sessions. Topics included context simulations, intelligent information dissemination, service provisioning, and QoS- and QoE-based algorithms, alongside managing mobility data and user-centric service selection. These discussions provided insights into the state of the art in management for ubiquitous communications and pointed to future research directions. The keynote by John Krumm from Microsoft Research focused on utilizing GPS data, covering models, predictions, location privacy, and road map creation, and concluded with practical tools and project ideas.

Economic perspectives in network management have garnered significant attention recently. The Third Workshop on Economic Traffic Management (ETM 2010) continued the success of previous events held at the University of Zürich in 2008 and 2009. ETM 2010 aimed to provide scientists, researchers, and operators a platform to present innovative research on ETM mechanisms, discuss new ideas, and enhance collaboration in the economics-technology interplay. Co-located with the International Teletraffic Congress (ITC22), this event united a rapidly growing scientific community. The concept of ETM has arisen from the presence of various stakeholders active in the Internet, each with distinct incentives and interests, whether competing or complementing one another in the service provider value chain. To create a win-win scenario for all parties involved—including end users, Internet Service Providers (ISPs), telecommunications operators, and service providers—new incentive-based approaches have been developed, tested, and even commercially implemented under the umbrella of Economic Traffic Management. ETM mechanisms focus on enhancing network efficiency, such as cost reduction, while simultaneously improving the Quality of Experience (QoE) for end users and applications.

This volume of the Lecture Notes in Computer Science series presents papers from the ICQT 2006 workshop, the 5th International Workshop on Internet Charging and QoS Technology, held in St. Malo, France, alongside ACM SIGMETRICS. The workshop addressed the urgent need for viable business models and pricing schemes for QoS-guaranteed services, which are crucial for diverse business opportunities. The interplay of technical and economic perspectives is essential for application developers, business architects, network providers, service providers, and customers. Key topics include identifying innovative service charging solutions, assessing their technical feasibility, and integrating technical and economic mechanisms to facilitate fast, guaranteed, and efficient service charging. These discussions are vital for the future evolution of the Internet and form the core focus of the ICQT workshop series. The first ICQT was held in 2001 in Vienna, Austria, as part of the Annual Meeting of the German Society for Computer Science and the Austrian Computer Society, with subsequent workshops in 2002 in Zürich, 2003 in Munich, and 2004 in Barcelona.

This book constitutes the joint refereed proceedings of the 5th COST264 International Workshop on Networked Group Communications, NGC 2003, and the 3rd International Workshop on Internet Charging and QoS Technologies, ICQT 2003, held in Munich, Germany, in September 2003. The 25 revised full papers and 6 revised short papers presented were carefully reviewed and selected from a total of 78 submissions. The papers are organized in topical sections on application multicast support, anycast and search in peer-to-peer networks, peer-to-peer systems, security and multicasting, multicast mechanisms, control algorithms, multicast pricing and traffic, routing and economics, and pricing and resource management.

This volume of the Lecture Notes in Computer Science series contains the set of papers accepted for publication at the colocated QofIS/ICQT 2002 workshops, i. e. the 3rd COST Action 263 International Workshop on Quality of future Internet Services (QofIS) and the 2nd International Workshop on Internet Charging and QoS Technology (ICQT), both of which took place at the ETH Zric h, Switzerland, hosted by the Computer Engineering and Networking Laboratory, TIK. QofIS 2002 was the third in a series of highly successful technical workshops and meetings on Internet services within the framework of the COST Action 263 Q uality of future Internet Services , following previous events in Berlin, Germany in 2000 and in Coimbra, Portugal in 2001. ICQT 2002 was the follow-up to a vivid and extremely well-attended workshop on Internet economics and charging technology that took place within the framework of the Annual Meeting of the German Society for Computer Science (GI) and the Austrian Computer Society in 2001 in Vienna, Austria.
